> ...like LineageOS. But installing it is so difficult that only 1% of people have the technical know how to even attempt it...
Aside: there is also /e/OS (or MurenaOS - their naming is inconsistent). It is basically LineageOS that someone else installs for you so you get everything in a package [0].
They sell many phones, but it also runs nicely on Fairphones if you want a phone that you can repair (there is of course a compromise in price / performance there - depends on what matters to you the most).
What do you mean incompatible with LineageOS? In LineageOS you have to choice to install Google services like Google Play, or use the Aurora store.
In /e/os/ they have their own app store, App Lounge, with which you can install apps from Google Play through the Google Play API, similar to how the Aurora store does it. And you can also find open-source and PWA apps in it.
I use fdroid and aurora store for installing apps, and push notifications work nicely using microg. Of course microg needs to connect to G servers (no way around it), but at least it works and there is no G app running on the phone.
